Did you see him?  I certainly didn't notice! Here's what happened...

Jennifer Lopez was on stage presenting the award for Best Pop Solo Performance and Adele won.  And as she came up to the stage to accept her award, Ukrainian TV presenter Vitalli Sediuk approached her on stage and said, "It's such an honor to win this award!  I love you Adele!"

Well, JLo was having none of that and with one quick flick of her thumb, he exited the stage.  JLo kept her cool completely, enough that most of the world watching the telecast didn't notice a thing!

Sediuk was arrested immediately and spent the night in jail.  Evidently he's a repeat offender in terms of celeb harassment disguised as pranks.
